TWISTING ATTACHMENT FOR WINDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 499,666, dated une 13,1893.

Application filed August 6,1892.

'upon a suitable yarn receiver.

I have chosen to illustrate my present invention as applied to aspooling machine of a form heretofore patented to me, No. 404,831, June11, 1889, and in the drawings the driving drum or shell roll isrepresented for convenience as having its axis parallel to the side ofthe frame, but this is immaterial, and instead, the said drum or rollmay stand at right angles thereto as in United States Patents Nos.459,039 and 459,040.

Prior to my invention it has been customary to take cops of yarn andwithout twisting, wind the yarn, one or more strands upon a spool, andthese spools having the yarns so applied have been put into a twisterand two or more of said yarns have been twisted together by or through aspindle, but in my invention, the yarn on the cops or bobbins on whichthey were spun are doubled and twisted and wound in one operation onyarn carriers, such as spools or cones.

Figure 1, in vertical section and elevation represents a sufficientportion of a spooling machine with my present improvements added toenable myinvention to be understood; Fig. 2, an enlarged verticalsection of my improved doubling and twisting device detached from themachine. Fig. 3, is a view looking down on Fig. 2, below the dotted lineas. Fig. 4, is a View looking up from the dotted line 00; and Fig. 5, isa detail to be referred to.

The frame-work A, the cylinder 6 on the shaft 6 the shaft e havingsuitable wheels e and located within the shell roll h constituting adriving drum to rotate the yarn receiver a are and may be allsubstantially as in the patent referred to, said yarn receiver beingSerialNo. 442,333- (No model.)

either cylindrical or conical, or of any known and suitableconstruction, but instead of the shell roll, I might employ a soliddrum. I have herein shown but one driving drum,but it will be understoodthat a machine embodying myinvention will contain aseries of said drumsalong one or both sides, and when the said drums are used parallel tothe side of the frame, the wheels e for rotating them, may all bearranged on one and the same shaft 6 arranged lengthwise of the machine,and driven in any usual or suitable manner. My patent of the UnitedStates, No. 404,831, shows one plan of driving shafts suitable forrotating said drums when their axes are at right angles to the side ofthe frame. The traverse guide 72 will preferably be of the formrepresented in United States Patent No. 459,039, it having a foot toenter a crossing groove in the shell roll it constituting the drum, saidguide sliding on rods 2, 2, sup ported by suitable arms or brackets as 3suitably attached to the frame-work A. The lower girth A of the framehas connected to, or is provided with a bracket a, which latter supportsa stand a on which is a stud a which serves as a support for a pulley apreferably having a surface by which to frictionally engage and rotatethe head a carrying the spindles a two or more of said spindlescontaining and presenting the yarns to be twisted and woundintospoolform,the drawings representing the said yarns as in the form ofcops as when taken from a mule. The head at its lower side is shown'asprovided with a friction face a which may be of cloth, leather,india-rubber, or other usual material. The hub of the pulley a isrepresented as provided with a belt pulley a which receives the belt aderiving its motion from the cylinder 6 The bracket and stand arerepresented as confined together by a hollow stud I) having a shoulderto rest on the bracket, a nut b being shown as screwed upon the lowerthreaded end of the stud. This stud receives through it a stop-motionrod 0, and near its lower end the stud has a transverse opening for thereception of a pawl c, the pawl being represented as connectedadjnstably with the rod 0 by a suitable screw o The outer end of thepawl c engagesalit'terc mounted loosely on a stud c, said lifter beingso constructed that when turned on or about the stud, the lifter, theshape of which is shown by dotted lines Fig. 1, will act by one of itscorners or by its surface to lift the head a. from the wheel a and thusstop the rotation of the head with its spindles, or yarn holders. Thislifting device is represented as a disk or button having a portion ofits periphery slabbed oif as in Figs. 1 and 5, leaving two corners 4, 4,see Fig. 5. The head a has, as shown, a hollow hub 5 which receives atube cl, which at its upper end supports a disk 61' having its peripheryincased by a clearer 61 preferably a piece of cloth, the purpose ofwhich is by its action against the yarn to give tension thereto betweenthe rigid guide eye 61 below the disk, one eye for each yarn, and theeye 6 above the disk, the latter eye being carried by a dropleverfpivoted at f on a suitable stud f in the disk. The stop-motion rodhas fast on ita collar 9, see Fig. 2, the collar serving to limit thedescent of the rod, and above the collar, the rod has applied to itfrictionally a clutch 9 provided with depending pins or projections 8.This clutch rests at its lower side on the collar, and the pins lieoutside the collar and in the line of movement of the inner ends of thedrop leversf, but when a yarn going to the guide eye f breaks so as tolet a drop wire fall, then in such case the inner end of the drop wireas the disk rotates meets a pin next to it of the clutch and actingagainst the said pin rotates the said clutch, and with it thestop-motion rod 0 far enough to turn the lifting device 0 and break thedriving contact between the head a and wheel a Above the clutch the rod0 is provided with a friction device g shown as a piece of leather orother suitable f material held against the clutch by suitable devices asnuts. The yarn to be doubled and twisted is led from the eyes 6 to thestation-, ary eyes f 4 and thence preferably over a glass rod m to thetraverse device h before described.

From the foregoing it will be understood that the doubling and twistingdevices, shown detached in Figs. 2, 3 and 4, may be readily attached toa spoolin g machine so that the yarns carried by the attachment, may bedoubled and twisted on their way to the spools. It will be understoodthat should the driving drum be at right angles to the side frame as inPatent No. 459,039, that in such event the yarn will have to bepresented to the eye of the traverse guide, as in United States Pat-,ent No. 404,831.

is permitted to slip to thereby avoid breaking the pins of the clutches.

shell roll form of drum is the best form known to me. a

By the term cop as used in the claim I intend to include a wound mass ofyarn on a bobbin or tube.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. A hollow spindle; a rotating head connected thereto; a series ofspindles fixed on said head and adapted to receive and hold masses ofyarn taken directly from the spindle of a spinning machine; a device torotate said head; a series of drop levers; a hollow stud to support saidspindle, a drop rod extended through said spindle and stud, and devicesactuated by said rod to arrest the rotation of said head, combined witha spooling mechanism consisting essentially of a drum to rotate thespool or device upon which the twisted yarn is to be wound, and atraverse mechanism whereby the spun yarns may be directlydoubled,twisted and wound all at a single operation, substantially as described.

2. The rotary driving drum of a spooling machine, and its co-operatingtraverse guide, combined with a rotating head adapted to receive andcarry masses of yarn taken directly from a spinning machine; a hollowspindle upon which said head is mounted; a stop motion rod extendedthrough said spindle; a lifter adapted to be actuated from said rod; anddrop levers to control the movement of said rod, the combination beingand operating substantially as described, whereby upon the breaking of ayarn the lifting device stops the rotation of the head, substantially asdescribed.

3. The rotating head, the hollow stud about which it rotates, aconnected disk having drop wires, and means to rotate said head,combined with a lifting device to lift the rotating head from itsactuating means, a stop rod, a clutch thereon,and means between the saidstop-rod and lifting device, to operate, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
